A: When a guy gets soapy water up his urethra after washing his genital area.

B: When an unlucky guy, uneducated in what and what not to use as lube, attempts to use soap to start whacking it

Soap Dick is commonly caused by the old fashioned bar soap (which should be avoided for washing your genital area AT ALL COSTS) but shampoo and body soap are also possible things that can cause Soap Dick. It causes a horribly painful burning sensation throughout the inside of the head of the penis. Soap Dick usually does not go away until you flush out the soapy water by urination, which is extremely painful, but luckily it doesn't last long.
